For anyone interested in pictorial history, the Bettmann Archive in New York City is known to be a small cellar brimful of priceless items which trace visually the progress of man. Its founder, Dr. Otto L. Bettmann, has spent the majority of his 52 years collecting pictures, and his medical files alone number over 10,000 old prints, woodcuts, and cartoons relating to every conceivable medical topic.
